Water temperature

[Hellarts]

Hi guys, would like to ask if my tank water is consistently temp range at 29.8-30.6°c, is it a good thing or will harm my fishes?
(No heater is in the tank)

Bro how can u achieve that temperature without heater? In SG, avg temp should be in the range of 27 -29℃

What fish u are keeping? If arowana, I saw some thread in the past that if the temp is too high, it will eat more and tend to age faster. Maybe some arowana specialist can advise in detail

constancy is good fluctuation is bad.

Pumps, lightings and placement of tank will affect the temp of water.
height of the water will also reflect diff temp
Unless the tank is place inside a/c room or outdoor...no heater or chiller is req for aros.

Put your hand in the water...if is warm den u shud do some troubleshooting on the cause...
China made pumps usually gives off alot of heat.
Submerged lighting too.

I not sure but I always use a test ph the temp will show that range.
I'm keep arowana and some bichirs.
Will the temperature be affect from closing all window at my house causes this?

There is no light submerged inside and the only pump is inside the tank is eheim 1262.
How am I supposed to do as I have no space for chiller.

Ok you are asking about the temp suitability.

I personally find 28-30 deg C is fine. Too low temperature <27 will reduce the aro appetite and find it easier to get white spot diseases. Too high temp >32 will greatly reduce the oxygen content in the water and aro will easily get "wrinkle" on the face area after longer period. However their aro appetite will greatly increase. Normally higher temp is for treatment purposes.

Temp of water are contribute by

1) electrical equipments submerge in the water (pump/powerhead/llights submerge) or even indirect contact of water like strong lights T5/lousy external canister etc.

2) Room ambient temp. You can never be lower than your room temp unless using form of colling on the tank water

Hmm I'm using Dymax T5 light set but is aquazonic supersun 12k tube and rainbow led light for red does this will affect it?😓 and my canisters is eheim 2260 I doubt is Because of this.

And I do not have and coil in my tank. But my house is almost 24/7 all window close. Will this affect it?

T5 type of light will depend on the nos of tube used to generate heat directly to tank water surface. For LED light the heat is generated away from the tank water.

For your house 24/7 windows close it will affect air circulation. This will gradually affect the room temp over time.

You can do a simple test if you really would like to know.

1) Check your house temp (especially the area near your tank)
2) This temp will be the same as your tank water if there are "NO" equipment connected or turn "ON"
3) On your lights for a few hours and see if there are change of temp.
4) Next will be your filter and see the temp change.

My best guess will be the light will generate more heat than your external filter. However this is base on condition that you use a good pump (generate less heat) for your 2260.

Lastly on your account that your house is 24/7 window close your house temp could be at least 27-29 degC which is normal. So the additional 1 or 2 deg could be from equipments.

The temp on your tank I find is still not too hot unless you are thinking of lowering the temp.

Okay I will take noted of all the things that may affect it.
I will try I take the temperature again when I open the window for air to come in.
And check when I off my light as I check is always with my lights on.

I just want to know if this range temp with cause any stress to my fish.
